Difference between Eubacteria and Archaebacteria

Eubacteria

Monerans
can be classified into three major groups: the eubacteria (True bacteria),
cyanobacteria (blue green algae) and archaebacteria (ancient bacteria). The
eubacteria are the commonly encountered bacteria in soil, water and living in
or on larger organisms, and include the Gram positive and Gram negative
bacteria.

Archaebacteria: Purple Sulphur Bacteria

The archaebacteria
grow in unusual environments such as salt brines, hot springs and in the ocean
depths. They are a group of most primitive prokaryotes which are believed to
have evolved immediately after the evolution of the first life. They are of
three types:-methanogens, Halophiles and thermoacidophilies.
